BICYCLE.

SPECIFICATION forming part of Letters Patent No. 439,400, dated October 28, 1890.

Application led May 10,1890. Serial No. 351,352. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE HARRIOTT, a subject of the Queen of Great Britain, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Bicycles, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to new and useful improvements in bicycles of that kind known as Safety 5 and the invention consists in the improved construction and arrangement of the seat and seat-supports, all as more fully hereinafter described, and shown in the accompanying drawings, in which- Figure l is a side elevation of a bicycle embodying my improvements. Fig. 2 is an enlarged elevation of the seat, partly in section. Fig. 3 is a plan of Fig. 2, with some of the parts shown in dotted lines only. Fig. 4 is a cross-section through the tension device on line c c of Fig. 2. Fig. 5 is an end elevation of the tension device. Figs. 6 and 7 are detached perspective views of the plates forming the seat-frame.

A is a steering-wheel, and A the drivingwheel, both substantially of the same diameter.

B and B are the front and rear forks, between the arms of which said wheels are mounted, respectively.

C is the front upright, preferably formed of steel tubing.

O2 is a steering-lever secured to a spindle C', which engages into the front fork-upright and is adjustably secured therein by means of a clampingcollar CB, which engages upon a reduced and slitted portion O4, formed on the upper end of the upright, and is provided with a clamping-screw Gwhereby the tightening of said screw clamps the parts together.

D D are two collars secured upon the front upright and provided with rearwardly-extend ing lugs D2 DB, which forni the steering-head, to which the front end of the spine is pivotally connected.

The arln Fis formed in one piece with the brake-shoe F. It is pivotally secured to the knuckle D4, and extends forwardly on top of 5o the wheel, and is guided between the upper ends of the arms of the front fork.

The brake-rod F2 is pivotally connected at its lower end to the brakeshoe and its upper end to the brake-lever F3, which latter is piv- 5 5 otally secured to the steering-lever. The coupling or turn-buckle E* in the brake-rod permits of its being lengthened or shortened.

The spline H is hollow and preferably made of steel tubing curved at its forward end over 6o the front wheel, extending horizontally to the rear and joined to .the rear fork to form a Y rigid frame. Upon this frame is mounted in suitable bearings the crank and sprocketshaft I of the driving-gear, which consists of the usual cranks, sprocket-wheels, and chain.

J is the rear upright secured at its lower end to the frame, curved at its lower portion over the front part of the rear wheel, and then extending vertically upward. It is pref- 7o erably formed of steel tubing and provided at its upper end with the clamping-collar K, by means of which the seat-supporting post L is vertically adj ustably secured in the upper end of the upright. This post has a grooved arm L at its upper end at right angies and carries the seat. This seat consists of the usual leather saddle M, secured at its front and rear end, respectively, to the inet-al frame-plates N and O, and which are sup- 8o ported upon front and rear springs P and Q. Each of these springs is formed of one piece of suitable springwire, with a pair of coils a connected on top bya rectangularly-bent portion b and with the projecting ends c. These S 5 springs are engaged with the portions b into suitable seats el d', formed on the plates N and O, respectively, and with the straight end portions c into sockets formed in the sliding plates R, which form part of the seat 9o block. This consists of the bed-plate S, provided with a sleeve T on the under side for adjustably securing it with a set-screw T upon the grooved arm of the seatsupport ing post L. On top of the bed-plate is supported in bearingsU the right and left handed spreader screw V', engaged, respectively, into screw threaded sockets of the sliding plates R. Between the bearings the screw is providedwith ahcadWforturningit bymeans of a wrench, all so arranged that by turning the screw in the proper direction the two sliding plates R R, which have a tenon-and-rnortise engagement with the bed-plate S, are spread apart, and thereby bring the springs P and Q under any desired tension required to keep the saddle M taut. This construction is obviously simple and permits the stretching of the saddle without displacing it from its adjusted position. At the saine time it is readily mounted and dismounted, and affords easy riding, a suitable inclination being given to the saddle by making the coils of the rear spring of larger diameter than the coils of the -front spring.

` By providing the arm L" of the seat-supporting post with the longitudinal groove and engaging the said screw T into this groove the seat maintains its proper position when the seat-block is adjusted. The coils a of the springs are on both sides of the connection with the saddle, and the rectangular bends b.

are seated inthe frame-plates and hold the saddle against any displacement and bring the tension of the springs to stretch the sad= dle longitudinally. The improvement in the front upright and the parts connected therewith I have made the subject of a separate application for Letters Patent, filed May 13, 1890, Serial No. 351,700.

What I claim as my invention is- 1. In a bicycle, the combination, with a seatsupporting post L, of the bed-plate S, adjustably secured thereto, the sliding plate R onthe bed-plate, the spreader-screw V adjustably connecting the sliding plates by right and left hand threads, respectively, and secured in bearings upon the bed-plates S, the front and rear springs P and Q, having arms c, secured in sockets in the sliding plates R, and the saddle M, secured to the springs P and Q, respectively, substantially as described.

2. In a bicycle, the combination, with the seat-supporting post L, of the bed-plate S, adjustably secured to said post, the plates R, slidingly engaging with the bed-plate S, the

spreader-screw V', providedy with right and left hand screw-threads at opposite ends and engaging with the plates R, the bearings U, in which the spreader-screw is supported upon the bed-plate, the head W of the spreaderscrew arranged between said bearings, the front and rear springsP and Q, provided with arms c, engaged to the sliding plates R, respectively, and with the straight portion b, the saddle M, provided with the frame-plates N and O, secured to the opposite ends of the saddle and provided with the seats d, into which the springs are engaged, substantially as described. v

3. In a bicycle, the combination of the seatblock provided with the longitudinally-adj ustable plates R, of the saddle M, provided with frame-plates O and N, secured to opposite ends thereof, the springsPQ, each formed with two coils at both sides of its connection with the saddle, and with the coils of the rear springlarger than the coils of the front. spring, the angularly-bent portions b of these springs engaged in sockets d d of the frame-plates, and the straight ends c of these springs engaged into sockets of the sliding plates R, respectively, substantially as described.

4. In a bicycle, the combination of the vertically-adj ustable seat-supportin g post L, having the longitudinally-grooved arm L', and provided with a set-screw engaging into the groove of the arm L', the plates R, having a sliding dovetail mortise-and-tenon engagement upon the opposite ends of the bed-plate, the screw V journaled in bearings U upon the bed-plate and provided with the head W, and right and lefthanded screw-threads upon its opposite ends, engaging with the plates R, respectively, and a saddle having its front and rear ends independently supported by the plates R R, substantially as described.

In testimony whereof I affix my signature, in presence of two witnesses, this 19th day of February, 1890. GEORGE HARRIOTT.
